I've discovered small differences shown by the diff images produced by the BatchDiffer. The effect popped up especially for A4-sized pages where the page size cannot be expressed in points as integer values. It was mostly a rounding problem. So prior to my little change [1] we ended up with the following:
[1] http://svn.apache.org/viewcvs?rev=264145&view=rev ----- PDF: << /Type /Page [..] /MediaBox [ 0 0 595 842 ] [..] and in the page stream: stream 1 0 0 -1 0 841 cm q [..] After my change, it's: stream 1 0 0 -1 0 841.8889770 cm q [..] ----- PostScript: %%Page: 1 1 %%PageBoundingBox: 0 0 595 842 %%PageHiResBoundingBox: 0 0 595.275 841.889 %%PageResources: (atend) %%BeginPageSetup << /PageSize [595 842] /ImagingBBox null >> setpagedevice [1 0 0 -1 0 841.88898] concat %%EndPageSetup Jeremias Maerki
